BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates generally to electrical wiring devices,and particularly to a modular electrical wiring device system.

2. Technical Background

The conventional method for installing electrical circuits includes a“rough-in” installation phase and a finish installation phase. In therough-in phase, conduit or cable is disposed throughout the structure inaccordance with the building plans. Junction boxes are installed atappropriate locations to house electrical connection points where two ormore conductors can be spliced together. Device boxes are installedthroughout the structure where electrical service is desired. After theboxes are placed, the electrical wires are pulled through the conduits(if provided) and all of the circuits are bonded such that the neutralconductors are connected to ground at or near the circuit breaker.

After the rough-in phase has been completed, the electrical wiringdevices are terminated, i.e., they are electrically connected to thewire leads. This part of the installation process is typically performedor supervised by a journeyman electrician. Subsequently, the groundstrap of the electrical wiring device is mounted to the device box. Oneor more electrical wiring devices may be mounted to a device boxdepending on the size of the device box. A single-gang device boxtypically accommodates one electrical wiring device, a two-gang devicebox will typically accommodate two electrical wiring devices, and so onand so forth. Once an electrical wiring device is installed inside thedevice box, a cover plate is disposed over the electrical wiring deviceto “complete the electrical enclosure” such that individuals are notexposed to “hot” electrical wiring after the electrical power is turnedON.

Non-limiting examples of electrical wiring devices include electricalreceptacles, ground fault circuit interrupters (GFCIs), switches, anddimmers. Other non-limiting examples include night light devices,charging devices, and accent lighting devices. Some wiring devices mayinclude combinations of the device functions listed above.

There are several drawbacks associated with conventional installationmethods and conventional wiring devices. Conventional wiring devicesoften do not make efficient use of space because they are typicallysized to fit a single-gang device box, whether they require this spaceor not. In addition, wire termination and device mounting (i.e.,connecting the ground strap to the device box) are tedious, timeconsuming, and therefore costly procedures. The same can be said ofmounting the cover plate to the electrical wiring device. What is neededis an electrical wiring system that addresses these concerns.

Another drawback relates to multi-gang installations. The finished lookis often ragged because the plurality of electrical devices and theirrespective cover plates are typically not in alignment. In fact, thevarious devices re often misaligned in all three dimensions. What isneeded therefore is an electrical wiring system that addresses the abovestated misalignment issues.

Retrofitting an electrical installation can also be problematic from afinished look standpoint because the device box (usually an old workbox) may not be precisely aligned to the plane of the existing wallsurface. This is especially true if the wall surface itself is uneven.There are also safety drawbacks to retrofitting an existing electricalinstallation. After remodeling is substantially finished, homeownersoften seek to replace the existing wall plates with ones that bettermatch the new décor. Thus, a homeowner may inadvisably remove thefaceplate cover from an energized wiring device and inadvertently becomeexposed to a shock hazard from the “hot” electrical wiring. What isneeded therefore is a wiring system that protects homeowners andoccupants from the risk of shock or electrocution when the cover plateis removed.

SUMMARY OF THE INVENTION

The present invention addresses the various needs described above byproviding a rigid frame that “completes the enclosure” while supportinga variety of modular electrical wiring devices. The modular electricalwiring devices of the present invention make efficient use of space byallowing up to three devices to be installed within a single gang devicebox. In addition, the frame of the present invention eliminates the needfor mounting the electrical wiring device to the device box. Moreover,the modular electrical wiring devices of the present invention do notrequire fasteners to be securely installed within the device box.Because the frame and the modular device(s) disposed therein completethe enclosure, no cover plate is needed. The cover plate is replaced byan aesthetic overlay that can be removed at any time without exposingthe homeowner to shock or electrocution. As its name suggests, theaesthetic overlay of the present invention may be comprised of a varietyof decorator materials without regard to the structural considerationsthat are concomitant with completing the enclosure. Finally, because theframe of the present invention completes the enclosure, it may beemployed with new construction, old construction or retrofits.

One aspect of the present invention is directed to an electrical wiringsystem that includes a frame configured to be mounted to a device wallbox installed in a structure. The frame includes a first edge formedaround a peripheral portion of the frame. The first edge is configuredto substantially abut a surface of the structure disposed around thedevice wall box. The frame assembly further includes a frame openingcorresponding to at least one gang opening. The frame openingsubstantially defines a second edge configured to extend inwardly towardthe device wall box interior such that the frame opening provides accessto the device wall box interior. At least one modular device isconfigured to be disposed within the frame opening to complete thesystem enclosure such that the device wall box interior is substantiallyinaccessible. The at least one modular device is selected from a groupof modular devices that includes at least one modular electrical wiringdevice and at least one alignment device. An aesthetic overlay isconfigured to be removably coupled to the frame assembly. The aestheticoverlay includes an overlay opening configured to provide access to atleast a portion of the at least one modular device.

In another aspect, the present invention is directed to an electricalwiring system that includes an electrical wiring system that includes aframe configured to be mounted to a device wall box installed in astructure. The frame including a first edge formed around a peripheralportion of the frame, the first edge being configured to substantiallyabut a surface of the structure disposed around the device wall box. Theframe assembly further including a frame opening corresponding to atleast one gang opening. The frame opening substantially defines a secondedge configured to extend inwardly toward the device wall box interiorsuch that the frame opening provides access to the device wall boxinterior. At least one modular device is configured to be disposedwithin the frame opening such that an interior of the device wall box issubstantially inaccessible. The at least one modular device is notconfigured to connect to the device box. The at least one modular deviceis selected from a group of modular devices that includes at least onemodular electrical wiring device and at least one alignment device. Theat least one electrical wiring device module is configured to bedisposed within the frame opening in a plurality of spatialorientations. The at least one modular electrical wiring device furtherincludes a self-grounding mechanism configured to engage a portion ofthe frame when the at least one modular electrical wiring device iscoupled within the frame opening in any one of the plurality of spatialconfigurations.

As embodied herein, and depicted in FIGS. 1A-1B, perspective views of aframe member 10 in accordance with the present invention are disclosed.FIG. 1A is directed to the rear side 10-2 of the frame member 10,whereas FIG. 1B is directed to the front side 10-1 of the frame member10. The frame member 10 is configured to “complete the electricalenclosure” when one or more modular electrical devices (30, 40 or 50)and/or modular alignment connectors 20 are properly installed within theframe opening 10-13 such that the device wall box interior issubstantially inaccessible. Stated differently, instead of using aconventional wall plate to complete the enclosure, the frame member 10is used to prevent individuals from being shocked or electrocuted byconcealing all electrical wiring under the frame 10 within the devicewall box interior.

Thus, a frame enclosure lip 10-5 is disposed around the perimeter of theframe 10. The frame enclosure lip 10-5 is configured to substantiallyabut the wall surface 1 (not shown in this view) such that a front edgeof a properly installed wall box does not substantially touch the rearside 10-2 of the frame 10. This is true even when old work boxes aredeployed. Old work boxes, of course, have flanges that are mounted tothe outer surface of the wall surface 1. The frame enclosure lip 10-5raises the rear surface 10-2 overtop the work box to avoid anyinterference with the flanges and prevent the frame 10 from contactingthe wall surface 1.

As shown, the frame 10 includes a frame opening 10-13 that has aninterior serrated edge or lip 10-6 that is configured to mate with themodular alignment conductors 20 and/or the electrical wiring devices 30,40, 42 or 50 in the manner disclosed below. Once the electrical wiringdevice and/or the modular alignment connectors are installed within theframe opening 10-13, the enclosure is completed. The interior serratedlip 10-6 extends along lateral portions of the frame opening 10-13 toadjoin a connector landing element 10-7 disposed at either end of theframe opening 10-13. The interior serrated lips 10-6 and the connectorlanding elements 10-7 extend perpendicularly around the entire frameopening 10-12 to form a rim or skirt that is inserted inwardly withinthe device box interior during installation. Accordingly, the regionunder the rear frame surface 10-2 between the outer enclosure lip 10-5and the interior rim (i.e., serrated lips 10-6 and landing 10-7) isdisposed over the wall surface 1. Once the wall box fasteners 10-10 areinserted into the fastener slots 10-12 and tightened, the interior ofthe device box is accessed via the frame opening 10-13. After deviceinstallation, however, the frame opening 10-13 is completely occupied bysome combination of modular wiring devices (30, 40, 42 or 50) and/ormodular alignment connectors 20 to thereby complete the enclosure. Allof the wiring is under the frame assembly and cannot be accessed.

As embodied herein and depicted in FIGS. 2A-2D, perspective views of amodular alignment connector 20 in accordance with the present inventionare disclosed. The modular alignment connector 20 is said to be modularbecause it adjusts and aligns the size of the frame opening such thatvarious combinations of wiring devices (e.g., 30, 40, 42) disposed in avariety of spatial orientations are used to complete the frame opening10-13 when they are installed therein.

FIG. 2A shows a front major surface 20-1 of the modular alignmentconnector 20 (when it is inserted within the frame opening 10-13). Thefront major surface 20-1 of the modular alignment connector 20 has awidth of approximately 11.2 mm and a length of about 45 mm. One pair ofthe alignment connectors 20 are the same size as a one-module electricalwiring device. The front major surface 20-1 includes a front connectorflange 20-6 which is configured to fit within the frame connector seat10-14 when the connector is inserted within the frame 10. The modularalignment connector 20 also includes bending snap arms 20-3 and spacertangs 20-4 disposed on either side of the connector 20. A spacer channel20-5 is disposed between the snap arm 20-3 and the spacer tang 20-4. Astheir name suggests, the snap arms 20-3 are used to “snap” the alignmentconnector 20 into the frame opening 10-13. Subsequently, the spacer tang20-4 is pressed into the spacer channel 20-5 to lock the modularalignment connector 20 into the frame opening 10-13. The locked snaparms 20-3 retain the alignment connector 20 within the frame opening10-13 thereafter. Stated differently, when a spacer tang 20-4 isinserted into a channel 20-5, the snap arm 20-3 can no longer deflectinwardly and thus cannot be removed from place. The snap connectassembly (20-3, 20-4, and 20-5) is configured to withstand at least 50foot-pounds of pulling force.

FIG. 2B shows the modular alignment connector 20 rotated 180° withrespect to the view provided by FIG. 2A. The front stabilizing plate20-6 and the rear connector flanges 20-7 form a connector channel 20-8that is configured to grip the frame connector landing 10-7 (See FIGS.1A-1B). The front stabilizing plate 20-6 is seated on the frameconnector seat 10-14 when the alignment connector 20 is inserted intothe frame opening 10-13. The purpose of the front stabilizing plate 20-6is to help the connector 20 retain its position within the frame opening10-13 by preventing it from being pushed inwardly and through frameopening 10-13.

FIG. 2C is a rear view of the modular alignment connector 20. This viewshows a rear major surface 20-2 that is supported underneath by devicestop elements 20-9. Like the serrated stop elements 10-60 of theserrated lip 10-6, the device stop elements 20-9 are configured toengage and mate with the device snap elements formed in the modularwiring device housing (See elements 30-2, 40-2, etc., depicted in FIG.5) to complete the electrical enclosure. This snap-fit arrangement fixesthe modular wiring device (30-2, 40-2) within the opening 10-13 suchthat it cannot move laterally or longitudinally within the frame opening10-13 when snapped in place. Stated differently, the interior serratedlips 10-6 and device stop elements 20-9 serve to secure and align theelectrical wiring device (30, 40, 50, etc.) within the frame opening10-13.

FIG. 2D shows the modular connector 20 rotated 180° with respect to theview provided by FIG. 2C. When inserted into the frame opening 10-13,the rear stabilizing plate 20-7 bears against edges of the connectorlanding 10-7 (See FIGS. 1A-1B). Again, the front stabilizing plate 20-6and the rear stabilizing plate 20-7 form a channel 20-8 that restrictsthe movement of the modular alignment connector 20 after being seated onthe connector seat 10-14. As the connector 20 is moved to this seatedposition, bending snap arms 20-3 are deflected inwardly by the interiorserrated lip 10-6 until they clear and snap back outwardly into theserrations. Again, the bending snap arms 20-3 prevent the connector 20from sliding or moving out of its seated position.

FIG. 3 is a detail view of the modular alignment connector 20 depictedin FIGS. 2A-2D. This detail view clearly shows the bending snap arm20-3, the spacer tang 20-4, and the spacer channel 20-5 formedtherebetween. Again, if the space tang 20-4 is rotated downwardly intothe channel 20-5, the snap arm 20-3 cannot deflect inwardly. Thisfeature locks the connector 20 within the frame opening 10-13.

Referring to FIGS. 4A-4E, illustrative views showing installationdetails of the frame 10, modular alignment connector 20 and anelectrical wiring device 40 are disclosed. As shown in FIG. 4A, onemodular alignment connector 20 is locked into one end of the frameopening 10-13, while another alignment connector 20 is shown beinginserted into the other end of the frame opening 10-13 (See arrow A).FIG. 4B shows the two connectors 20 locked into opposite ends of opening10-13. In FIG. 4C, a wiring device 40 has been inserted between themodular alignment connectors 20. The back body 40-3 of device 40 isshown to be bearing against the spacer tangs 20-4 to thus prevent themfrom moving inwardly. Stated differently, the back body 40-3 preventsthe spacer tangs 20-4 from being removed from the channel 20-5 such thatthe modular alignment connectors 20 cannot be removed from the frameonce a wiring device 40 has been installed inside the frame opening10-13. FIG. 4D is a side view that shows how device 40 was moved in thedirection of the arrow “A” into the frame opening 10-13 duringinstallation. FIG. 4E shows the device 40 fully installed within theopening 10-13.

As embodied herein and depicted in FIGS. 5A-5D, perspective views of themodular electrical wiring device types in accordance with the presentinvention are disclosed. FIG. 5A shows a one-module electrical wiringdevice 30. The user interface portion 30-1 has a width of approximately22.5 mm and a length of about 45 mm. Thus, two one-module devices 30placed side by side will complete a 45 mm×45 mm square. The back body30-3 has snaps 30-2 at either end and is configured to fasten the device30 to either the interior serrated lips 10-6 or to the device stopelements of the modular alignment connectors 20, depending on how thedevice is oriented with respect to frame 10 during installation (seeFIGS. 6A-6G.)

FIG. 5B shows a two-module electrical wiring device 40. The dimensionsof user interface portion 40-1 are approximately 45 mm×45 mm. The backbody 40-3 has snap elements 40-2 disposed at either end. Like the snapelements 30-2 in FIG. 5A, the snap elements 40-2 are configured tofasten the modular device 40 to the interior serrated lips 10-6 or tothe modular alignment connectors 20, depending on how it is orientedwith respect to frame 10 during installation (see FIGS. 6D-6K.) Thenumber of snaps provided in the various sides of the modular devicescould be, but is not necessarily, equal in number. In an embodiment ofthe invention, one side of the device has two snap elements whereas anopposite side has only one snap element. Removal of a modular wiringdevice from the frame 10 is thus made easier by starting with the sidewith the single snap 40-2.

FIG. 5C discloses a “two-module front/three-module back” electricalwiring device 42. In this embodiment, the user interface portion 42-1 isabout 45 mm×45 mm and the back body is approximately 67.5 mm in length.The back body 42-3 includes snap elements 42-2 disposed on either sidethereof. The snap elements 42-2 are configured to fasten the device 42into the frame opening 10-13 via the interior serrated lip portions10-6.

FIG. 5D is a three module device that includes a user interface portion50-1 that is approximately 45 mm×67.5 mm. The back body 50-3 includessnap elements 50-2 disposed on either side of the device 50. The snapelements 50-2 are configured to snap into the frame opening 10-13 bymating with the interior serrated lips 10-6.

Referring to FIGS. 6A-6N, illustrative views showing variouscombinations of modular electrical wiring devices installed within asingle gang frame member 10 are disclosed. As inferred by the discussionimmediately above, an unoccupied frame opening 10-13 (see, e.g., FIGS.1A, 6C, etc.) has dimensions 45 mm (W)×67.5 mm (L). This allows theframe to accommodate various combinations of electrical wiring devicesand modular alignment connectors 20 if their combined surface areaequals 3,037.5 mm² (i.e., 45 mm×67.5 mm). This area corresponds, ofcourse, to the front surface area occupied by the three-module wiringdevice 50.

In reference to FIGS. 6A-6B and 6H-6K, a pair of modular alignmentconnectors 20 is disposed at either end of the frame opening 10-13. Aspreviously stated, the front major surface 20-1 of the modular alignmentconnector 20 has a width of approximately 11.2 mm and a length of about45 mm. The pair of connectors 20 thus occupies the same amount of spacethat a one-module wiring device occupies. Stated differently, themodular alignment connectors 20 can be used with certain wiring devices,or certain combinations of wiring devices, when they are required to“complete the enclosure.” In FIG. 6A, for example, two one-moduledevices 30 are disposed lengthwise between the two connectors 20 tocomplete the enclosure. In FIG. 6B, two one-module devices 30 aredisposed widthwise between the two connectors 20 to complete theenclosure. In FIG. 6H, a two-module device 40 is disposed uprightbetween the two connectors 20 to complete the enclosure. In FIGS. 61 and6K, a two-module device 40 is disposed sideways between the twoconnectors 20 to complete the enclosure. In FIG. 6J, a two-module device40 is disposed upside down between the two connectors 20 to complete theenclosure. Thus, the electrical wiring devices of the present inventionlend themselves to a variety of spatial orientations within the frameopening 10-13.

In FIGS. 6C-6G and 6L-6N, the system does not require the use of themodular alignment connectors 20. For example, FIGS. 6D-6G show variouscombinations and orientations of one-module wiring devices 30 and atwo-module wiring devices 40. Of course, it is expected that thesecombinations should not require any alignment connectors 20 because aone-module device in combination with a two-module device occupies allof the three-module sized space provided by the frame opening 10-13.

FIG. 6L shows the frame opening 10-13 being fully occupied by one“two-module front/three-module back electrical wiring device 42, whereasFIGS. 6M and 6N show the frame opening 10-13 being fully occupied by onethree-module sized device 50.

FIG. 7 is a perspective view showing a three gang frame member 10-30with an illustrative combination of modular electrical wiring devices(30, 40, and 42) being installed therein. The three gang wall box 2 isinstalled within the wall surface 1 such that the frame enclosure lip10-5 extends around the periphery of the frame 10-30 to abut the wallsurface 1. Note that a multi-gang frame (10-20, 10-30, 10-40) employs“interrupted” gang separation ribs 10-31. The ribs 10-31 allow themodular alignment connectors 20 to be attached to the frame 10-30 insideindividual gang openings 10-13 and also provide the interior serratedlip portions 10-6 for the wiring devices (30, 40, and 42) as before.However, the ribs are interrupted by a gap formed in an intermediateportion thereof that is advantageous during the wiring process. When theelectrical wiring is being pulled through the opening 10-13 of the frame10, the gap allows the installer to pull all of the wires through at onetime without having to be concerned about whether the wires are properlymatched to their respective frame openings 10-13. Moreover, each set ofwires can be connected to their respective electrical wiring deviceswithout interference by gang separation ribs that span the opening fromtop to bottom. By virtue of the gang separation ribs 10-31, once eachset of wires is terminated to its respective wiring device, theelectrical wiring devices with their respective sets of wires can bemoved across the entire width of the multi-gang box and shifted intoplace in their respective installed locations.

FIG. 8 is a perspective view of a two gang frame member 10-20. Like theprevious embodiment, the frame 10-20 includes gang separation ribs 10-21which are also interrupted by a gapped portion in an intermediateportion thereof. The frame member 10-20 has a ground wire 10-9 attachedto it in accordance with the present invention. In particular, theground wire 10-9 is attached to the ground connection tab 10-8 thatextends from the connector landing portion 10-7 of the frame 10 (See,e.g., FIGS. 1A-1B). As explained below, the wiring device modules (30,40, 42 and 50) may be equipped with a self grounding terminal (See,e.g., ground terminal 40-10 at FIGS. 16A-16B) that is configured tocontact the ground tab 10-8. Thus, a convenient electrical groundfacility is provided by the present invention.

FIG. 9 is a perspective view of a three-gang frame member 10-30 inaccordance with the present invention. Like the other multi-gangembodiments, frame 10-30 also includes gang separation ribs 10-31 whichlikewise include a gap in an intermediate portion thereof. Frame 10-30is also equipped with a ground wire 10-9 in accordance with the presentinvention.

FIG. 10 is a perspective view of a four gang frame member 10-40 inaccordance with the present invention. Frame 10-40 includes gangseparation ribs 10-41 and with a ground wire 10-9. With respect to theprevious embodiments, like parts are designated by like reference numbernumbers.

With respect to FIGS. 11A-11B, rear views of the three-gang andfour-gang frame members 10-30 and 10-40 depicted in FIGS. 9 and 10 aredisclosed. Note that in the multi-gang embodiments greater than twogangs, fastener slots 10-12 are only provided in the corner locations.In the interior gangs, the fastener slots 10-12 are replaced by fastenerblanks 10-11. In addition, these rear views also show the manner inwhich the ground wire is connected to one of the ground connection tabs10-8. Regardless of the frame size, i.e., only one ground wire 10-9 isneeded per frame 10. One ground wire 10-9 need be bonded to a four-gangframe to provide ground connectivity between the premise ground and allof the devices (30, 40, 42, and/or 50) mounted on the frame 10. Byeliminating the need for individual grounding wires, the self-groundingfeature provides another efficient feature for the wiring and the deviceinstallation processes.

As embodied herein and depicted in FIGS. 12-14, exploded views ofvarious aesthetic overlay assemblies 60 in accordance with the presentinvention are disclosed. Once the electrical wiring devices (30, 40, 42or 50) and/or any modular connectors 20 are installed, each of theoverlay assemblies 60 may be removed from the frame 10 by the homeownerwithout any risk of being exposed to hot electrical wiring or hotelectrical components. Again, this is referred to above as frame 10being used to “complete the enclosure.” Stated differently, theaesthetic overlay 60 is not used to complete the enclosure and is notused to prevent shock or electrocution. Because the component parts,materials or material thicknesses of the overlay assemblies 60 cannotadversely affect safety they can be selected from a broad range ofmaterials including plastics, metals, wood, leather, wall paper, paint,laminated materials, and/or composite materials. Although theembodiments shown in FIGS. 12-14 are directed to single gangconfigurations, the principles set forth herein also apply to multi-gangconfigurations.

In reference to FIG. 12, the overlay assembly 60 includes an aestheticoverlay plate 60-1 that mates with an aesthetic support frame 60-2.Aesthetic overlay plate 60-1 shown in this view has a two-moduleaesthetic plate opening 60-10 that accommodates a pair of one-moduleelectrical wiring devices 30, a two-module electrical wiring device 40or a two-module front device 42 (See FIGS. 5A-5C). In an alternateembodiment, the aesthetic plate opening 60-10 is configured toaccommodate a three-module electrical wiring device 50 (See FIG. 5D). Athree-module opening can also accommodate any of the combinations ofelectrical wiring devices shown in FIGS. 6C-6G and FIGS. 6L-6N.

When a device combination employs the modular alignment connectors 20,the front major surface 20-1 of the connector 20 is recessed beneath theaesthetic overlay plate 60-1 and hidden from view by the overlay plate60 after installation. In an alternate embodiment of the presentinvention, the connector front major surfaces 20-1 may be flush with theouter surface 60-1 of the overlay plate and in full view. In thisembodiment, the front major surface 20-1 may be labeled or bear humanreadable indicia that identifies the purpose of the electrical wiringdevice or used to provide other useful information. The overlay plate60-1 may be formed of from a broad range of materials includingplastics, metals, wood, leather, wall paper, paint, laminated materials,and/or composite materials. In another non-limiting example, the plate60-1 may also be formed from a material that can be painted to match thecolor of the wall surface 1.

The support frame 60-2 is configured to snap onto and off of the frame10. The frame 10 includes ratcheting overlay snap devices 10-3 thatadjustably mate with frame support catches 60-3. Even when the wallsurface 1 is uneven, the adjustable ratcheting system described hereinallows the frame 10 to fit snuggly against the wall surface 1. Theoverlay plate 60-1 includes a plurality of overlay snaps 60-6 that alignwith corresponding snap openings 60-5 in the support frame 60-2 tocouple the aesthetic overlay plate 60-1 to the aesthetic support frame60-2. In one embodiment of the present invention, there can be twelveoverlay snaps 60-6 distributed around the periphery of the aestheticoverlay plate 60-1 to provide a secure bond between the plate 60-2 andthe frame 60-2.

The aesthetic plate is coupled to the frame 10 when the plate 60 isdisposed over the frame 10 such that the frame snaps 60-4 engage theside overlay snaps 10-4 disposed at intervals along the sides of theframe 10. When a user desires to change the aesthetic plate 60, a screwdriver or a similar tool can be inserted between the overlay removalcatch 60-7 and the overlay removal pry 10-3′. The leverage provided bythe screw driver must overcome the snap-in bond between the frame snaps60-4 and their respective side overlay snaps 10-4.

In reference to FIG. 13, an aesthetic overlay assembly 60′ in accordancewith another embodiment of the present invention is disclosed. In thisembodiment, the aesthetic overlay assembly 60′ includes a four-plyaesthetic overlay plate 60-1 coupled to the aesthetic support frame60-2. The aesthetic overlay plate 60-1 includes a top finish layer 60-20that is coupled to a metal backing plate 60-23 by a pressure sensitiveadhesive 60-22. The backing plate 60-23 may be implemented using anysuitable material such as a metallic material, a composite material or asuitable plastic material to provide rigidity to the otherwise flexiblelayers 60-20 and 60-22. The backing plate 60-23 includes plate posts60-27 that are configured to mate with the frame support post openings60-28 that are formed in the frame support plate 60-21. The framesupport plate 60-21 also includes support posts 60-25 which areconfigured to mate with the post openings 60-26 formed in the aestheticsupport frame 60-2.

FIG. 13 also shows a ground link 60-24 disposed between the aestheticplate assembly 60-1 and the aesthetic frame 60-2. Briefly stated, one ormore ground links 60-24 serve to connect the metal portions of theaesthetic frame assembly 60-1 to the frame 10 and by extension to theground wire 10-9 and premise ground. Obviously, if the backing plate60-23 is formed of a metallic material, the ground link 60-24 is neededto provide a conductive path from the plate 60-23 and the frame 10 toground. Those skilled in the art will appreciate that the ground link60-24 may be suitably employed in any of the embodiments describedherein.

As described above, the aesthetic support frame 60-2 includes framesupport catches 60-3 and frame snap catches 60-4. These elements areused to couple the aesthetic support frame 60-2 to the frame 10. Inparticular, the frame support catches 60-3 mate with the ratchetingoverlay snaps 10-3 and the frame snap catches 60-4 mate with the sideoverlay snaps 10-4 to couple the aesthetic frame 60-2 to the frame 10.

In reference to FIG. 14, an exploded view of an aesthetic overlayassembly 60″ in accordance with yet another embodiment of the presentinvention is disclosed. In this embodiment, the aesthetic overlay plate60-1 is implemented using a die-cast metal material. The die-cast metalmay be finished with any suitable material in any aesthetically pleasingmanner. The aesthetic overlay plate 60-1 is aligned and coupled toaesthetic support frame 60-2 by way of two interconnections. The firstinterconnection includes the aesthetic overlay support posts 60-31 whichare configured to mate with the post openings 60-32 formed in theaesthetic frame 60-2. The second interconnection includes the so-called“robin tails” 60-33 which are configured to mate with the “robin tailnests” 60-34. During installation, the posts 60-31 are aligned to thepost openings 60-32, and the robin tails 60-33 are aligned with thenests 60-34. In the next step, the posts 60-31 and the tails 60-33 areinserted into the post openings 60-32 and the nest openings 60-34,respectively. Finally, the tails 60-33, which at this point extendthrough the nest openings 60-34, are peened over an inside edge of therobin tail nests 60-34 such that the aesthetic plate 60-1 is secured tothe aesthetic frame 60-2. FIG. 14 also includes a ground link 60-24positioned between the aesthetic plate 60-1 and the aesthetic frame60-2. Like the previous embodiment, one or more ground links 60-24 maybe used to connect the metal plate 60-1 to the frame 10 and ground.

As embodied herein and depicted in FIGS. 15A-15D, various views of amodular electrical wiring device system 100 are disclosed. By way ofnon-limiting example, FIG. 15A shows a two-modular electrical wiringdevice 40 inserted into the frame 10, which is in turn, connected to thedevice box 2. Portions of the modular wiring device 40 and the frame 10in its entirety are covered by the aesthetic overlay plate 60 (Shown inFIG. 12). FIG. 15B is almost identical, with the exception that theaesthetic overlay plate 60′ OF FIG. 13 is used. FIG. 15C shows the samearrangement using the aesthetic overlay depicted in FIG. 14. FIGS.15A-15C show that each aesthetic overlay (60, 60′ and 60″) substantiallyabuts the adjacent wall surface 1 by virtue of the ratcheting overlaysnap 10-3.

In reference to FIG. 15D, a cross-sectional view is provided toillustrate the relationship between the aesthetic overlay assembly 60,frame 10, and the wall surface 1. In this view, a three-module wiringdevice 50 is depicted for ease of illustration. The frame's serrated lip10-6 is inserted within the wall box 2 opening to accommodate the wiringdevice 50 therewithin. The modular wiring device 50 includes snapelements 50-2 that mate with the serrated lip 10-6. The frame 10 isconnected to the wall box 2 via fasteners 10-10 which extend through theraised front surface 10-1 portion of the frame 10 to provide clearancefor the flange's of the old work box 2. The aesthetic overlay assembly60 fits overtop the frame 10 and device 50, and includes an opening60-10 that provides access to the user interface 50-1 portion of thewiring device 50. The aesthetic overlay frame 60-2 also includes theframe support catch 60-3 that engages the ratcheting overlay snaps 10-3.While this relationship was described above, it is seen clearly in thisview; the support catch 60-3 includes grooves that mate with theratcheting snaps 10-3 such that the overlay 60 can be adjusted upwardlyand downwardly relative to the wall surface 1. Again, this feature ofthe present invention allows the aesthetic overlay 60 to be adjustedsuch that it can be substantially flush with the wall surface 1 even ifthe wall is rather uneven. Moreover, the wall box 2 may be apre-existing wall box disposed in a pre-existing electrical distributionsystem or a new device box installed in a new installation.

As embodied herein and depicted in FIG. 16A, an exploded view of atwo-module electrical wiring device 40 in accordance with the presentinvention is disclosed. In this example, the electrical wiring device 40is shown as a full duplex receptacle. Those of ordinary skill in the artwill understand that the present invention may embody other wiringdevices such as GFCIs, AFCIs, mechanical switches, electronic switches,fan control devices, TVSS devices and the like. The modular device 40includes a user-interface 40-1, which in this example embodiment isimplemented by a cover member that has receptacle openings 40-16. Thecover member 40-1 is shown to include a labeling flange 40-15. Thelabeling flange 40-15 is designed to overlay the frame 10 or a modularalignment connector 20, depending on how the electrical wiring device 40is oriented during its installation in the frame 10.

Thus, the housing includes the cover 40-1, the back body member 40-3 anda separator 40-4 which is disposed therebetween. The separator 40-4, ofcourse, provides a dielectric barrier between the hot, neutral andground conductors to prevent short circuits. The hot and neutralconductors are not shown in this view because they are disposed underthe shutter assembly 40-5. Reference is made to U.S. Pat. No. 8,044,299and U.S. patent application Ser. No. 13/487,547, which are incorporatedherein by reference as though fully set forth in their entirety, for amore detailed explanation of the shutter assembly 40-5. The groundconnection is provided by the self-grounding terminal 40-10, which isdescribed in greater detail below in the discussion pertaining to FIG.16B. The full duplex receptacle 40 provides AC power to an electricalload via an AC power plug that is inserted into the receptacle openings40-16. The blades of the AC plug are configured to mate with the hot,neutral and ground electrical contacts in communication with theopenings 40-16.

In reference to FIG. 16B, a detail view of the self-grounding structure40-10 depicted in FIG. 16A is disclosed. The self-grounding feature40-10 includes an “L-shaped” ground strap 40-12 that accommodates theground receptacle terminals 40-13 as well as the dual self-groundingterminal contacts 40-14. When comparing FIG. 16A with 16B, it becomesapparent that the self-grounding terminal contacts 40-14 are accessiblevia the ground access windows 40-11 formed in the back body member 40-3.As described above and shown in greater detail below, the self-groundingterminal contacts 40-14 are configured to engage the ground connectiontab 10-8 or a portion of the serrated lip 10-6 (See FIGS. 1A-1B).

In reference to FIG. 17, a rear view of the modular system 100illustrating the self-grounding structure 40-10 depicted in FIGS.16A-16B is disclosed. The dual self-grounding terminal contacts 40-14allow the wiring device (30, 40, 42 and 50) to be oriented in a varietyof ways within the frame 10 while providing the self-groundingfunctionality. In this view, the frame opening 10-13 includes atwo-module device 40 disposed between two modular alignment connectors20. One of the dual self-grounding terminal contacts 40-14 engages theinterior serrated lip 10-6 (on the left side of the frame 10) to provideground connectivity between the grounding circuit of the electricalwiring device 40 and the frame 10. The ground connection is completed bythe ground wire 10-9 being connected to the frame 10 and the premisewiring. Again, the ground wire 10-9 is bonded to ground connection tab10-8 formed on connector landing 10-7. Of course, the other one of thedual self-grounding terminal contacts 40-14 that is disposed adjacentthe modular alignment connector does not provide a ground path forobvious reasons (the modular alignment connector is non-conductive).

In reference to FIG. 18, a front perspective view of the system 100depicted in FIG. 17 is disclosed. In this view, the electrical wiringdevice 40 is being inserted into the frame opening 10-13 such that oneof the dual terminal connectors 40-14 will engage the interior serratedlip 10-6 of the frame 10 while the other engages the modular alignmentconnector 20. The hot and neutral openings 40-16 of the electricalwiring device 40 are aligned with the major longitudinal axis (i.e., thelength) of the frame 10.

FIG. 19 illustrates the versatility of the system 100 because it showsthe hot and neutral openings 40-16 of the electrical wiring device 40being aligned with the major latitudinal axis (i.e., the width) of theframe 10. As before, the electrical wiring device 40 is being insertedinto the frame opening 10-13 such that one of the dual terminalconnectors 40-14 will engage the interior serrated lip 10-6 of the frame10 while the other engages the modular alignment connector 20.

FIG. 20 is yet another perspective view of the system 100 thatillustrates the versatility of the system 100. Like the previousembodiment, the hot and neutral openings 40-16 of the electrical wiringdevice 40 are aligned with the major latitudinal axis (i.e., the width)of the frame 10. Note however, that the frame opening 10-13 does notinclude any modular alignment connectors 20. This is because the system(in this Figure) will ultimately include a one-module device 30 (See,e.g., FIGS. 6D-6E) in combination with the two module device 40. In thisconfiguration, both of the dual ground terminal contacts will engageportions of the frame 10. One terminal contact 40-14 will engage theinterior serrated lip 10-6 while the other will engage the groundconnection tab 10-8. The dual ground terminal 40-10 of the one-moduledevice 30 (not shown in this view) will also engage the interiorserrated lip 10-6 and the ground connection tab 10-8.

As embodied herein and depicted in FIG. 21, a four gang embodiment ofthe modular system 100 employing the self-grounding terminal 40-10 inaccordance with the present invention is disclosed. In this embodiment,each of the four gang openings includes a two-module device 40 disposedbetween two modular alignment connectors 20. As described previously,the gang openings are separated by a gapped gang separation rib (i.e.,the rib has a gap in the mid portion thereof for wiring efficiencies).The self-grounding terminal contact 40-14 of the right most wiringdevice 40 contacts the frame 10-40 along the right edge thereof. Theself-grounding device contacts (40-14) of the other three wiring devices40 obtain electrical continuity with the frame 10 by contacting theirrespective gang separation ribs 10-41.

As embodied herein and depicted in FIG. 22, another four gang frameembodiment is disclosed. In this alternative embodiment, the system 100may be configured such that all four wiring devices 40 are individuallyconnected to their respective ground wires 40-9 while the frame 10itself is connected to a separate ground wire 10-9. This arrangement maybe employed, for example, when the electrical wiring devices (30, 40,42, and 50) include an isolated ground configuration. Those skilled inthe art will understand that electrical wiring devices with isolatedgrounds are often used to provide power to loads that are sensitive toelectrical noise. Instead of being grounded by way of wire 10-9, thesedevices have separate ground wires 40-9 that are connected together andbonded to a separate noise-free ground. Thus, the self-grounding featureof the present invention is not used when the electrical wiring devicesare equipped with their own individual ground wires (40-9).

As embodied herein and depicted in FIG. 23, another three gang frame10-30 embodiment of the present invention is disclosed. This embodimentis a variation of the three gang frames shown in, e.g., FIGS. 7, 9, and11A. In this embodiment, the wall box mounting holes 10-12 areimplemented as elongated slots that face the center of the frame. Theseelongated slots 10-12 permit the frame 10 to be rotationally leveledwith respect to the horizontal before the fasteners 10-10 (not shown inthis view) are tightened down to secure the frame to the wall box 2 (notshown in this view). The fastener holes are not provided at the centergang position because they would interfere with the aforementionedrotational alignment. Moreover, the corner fasteners suffice forsecuring the frame 10 to the wall box 2. The omission of those fastenersat the central gang locations is yet another example of how theinvention provides efficiency during the wiring process. Stateddifferently, the top fastener opening 10-12 and the bottom fasteneropening 10-12 are only provided for gang openings disposed between thelateral portion 10-15 of the frame and the gang separation rib 10-31.This translates to two gang, three gang and four gang implementations.

As noted previously, fastener location blanks 10-11 are provided in lieuof openings at interior gang locations. An installer may drill those outto enable wiring devices with mounting straps to be mounted there.Reference is made to U.S. patent application Ser. Nos. 12/861,619 and13/029,846, which are incorporated herein by reference as though fullyset forth in its entirety, for a more detailed explanation of electricalwiring devices that include mounting straps. In device of this type, theelectrical wiring is terminated by a plug member that is inserted into arear receptacle formed in the electrical wiring device. The plugconnection is used instead of wiring terminals to provide electricalcontinuity between the electrical wiring device and the electricaldistribution system. Of course, the present invention does not precludethe use of wiring terminals to provide electrical continuity between theelectrical wiring device and the electrical distribution system.
